I'm a finance guy who has been reading about NLP and sentiment analysis. Any introductory books on this subject that you'd recommend for a non-linguist interested in NLP and sentiment analysis? I'm well versed in python/R.
Sorry, I don't have any help, I'm just a regular joe looking at this stuff and taking particularly hacky ways to get the job done on the side (when I don't have other things going on. :-) ). The approach I've been taking initially is the bag-of-words approach. Looking forward I anticipate using some sort of ngram-based approach which clusters sentiment around phrases. These are stupid approaches, but I want to see how far I can push simple and stupid. ;)
